' MOLDING DEVICE.

22; all whom it may concern:

Be it known that I, ALDA F. HAWKINS, a

citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Molding Devices, of which the following is a specification. This invention relates to molding devices.

The object of the invention is to obviate the use of a gate and to core the casting as it is poured; and to do so in a simple, efficacious and expeditious manner.

In carrying out the invention I provide an elongated tubular member having its lower end shaped in accordance with the core desired and provided with parts through which the molten metal will flow into the mold. A funnel is formed at the upper end of the member to make pouring easier and a handle is also attached to the upper end of the member, whereby it may be rotated to shear off the metal at the ports.

The invention will be more readily understood'from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Figure 1 is a side elevation of a device embodying the invention,

Fig. 2 is a vertical sectional view through a mold with the device inserted therein and the casting metal filling in the parts, and

Fig. 3 is a crosssectional detail on the line 3-3 of Fig. 1. r

. In the drawings the numeral 1 designates a tubular shank having a reduced and tapered core-plug 2 at its lower end. Anannular shoulder 3 is had at the intersection of the parts 1 and 2. An enlarged shouldered head 4. is formed integral with the upper end of the shank. An annular boss 5 surrounds the shank immediately under the head. It

will be observed that the shank also tapers toward the plug. A handle 9 is mounted on an arm 9' extending laterally from the head 4.

A funnel or flared opening 6 is formed at the center of the top of the head and a cen tral tapered passage '7 leads from the funnel down intothe plug. Above the bottom of the passage and below the shoulder 3 Specification of Letters Patent.

concentric relation to the recess C and of a depth substantially equalto the length of the shank 1 from the boss 5' to the shoulder 3.' Thus when the shank is inserted in the opening E, the boss 5 will rest on the top of the cope and the shoulder 8 will be flush with the top of the recess 0 or the upper end of the mold cavity.

In using the device the shank 11 is inserted in the opening E, which it fits snugly. Molten metal is poured into the funnel 6 from which it flows down the passage 7 and outwardly through the ports 8 into the recess C and sump D. When the funnel fills the pouring is complete. The molder next gives the device a slight rotation by means of the handle 9, which causes the plug 2 to shear the metal at the ports 8, the shoulder '3 rotating on top of the casting. As the plug 1 and shank 2 flare upwardly, the device may be easily removed by a twisting movement.

The ports 8, passage 7 and funnel 6 will be full of the pouring metal when removed and to free the same the device is inverted and dipped in the pot of hot metal, whereby the chilled metal in the device loosens or melts and flows out as is obvious. The device is now ready for another casting.

It will be seen that the plug 2 acts as a core for the casting and neither a core nor a gate is required. The plug and shank havingra lower temperature than the molten metal will tend to chill the casting so that the shearing at the ports is readily accom: plished. The coring is likewise easily performed and the rotating of the plugs tends to finish the cored portion. It is highly desirable to core some castings because they may be made larger and greater strength had; this is particularly true of battery terminals, which are made of soft metal.

What I claim is:

1. A molding device including a tubular pouring and shearing member having a lateral outlet for discharging the metal, and means for rotating the member to shear the metal at the outlet.

' r 2, A molding device fugicluding a tubular pouring and shearing member having radial ports at its lower end for discharging the metal, and a handle at'the upper end. forv rotating the member to shear the metal at the ports. 7

3. A molding device including a head, a shank depending from the head, and a plug depending from the shank, the plug having a lateral discharge opening and the device having a passage extending through the head and shank to the plug and communieating with the discharge opening.

4. A molding device including a head, a shank depending from the head, a plug depending from the shank, the plug having a lateral discharge opening and the device having a passage extending through the head and shank to the plug and c0mmunieatin with the discharge opening, and a hand e for rotating the device to shear the pouredmetal at the discharge opening.

5,- A molding device including ahead, a

handle attached to the head, a tapered shank depending from the head, a reduced and taperediplug depending from the shank, and a bearing shoulder at the intersection of the plug and shank, the device having a funnel in the head and a passage leading from the funnel 'down through the shank into the plug, the plughaving radial ports leading from the passage below the shoulder.

6. A molding device including a rotatable pouring and shearing member having a pas- -sage for poured metaland an outlet for discharging the poured metal and for shearing the same when the member is rotated.

7. In a molding device, th e combination with a mold, of a rotatable member inserted in the mold and having a passage for poured metal andanoutlet to the mold, said member shearing the metal at its outlet when rotated.

In testimony whereof I atfiX my signature. ALDA F. HAWKINS.
